Embodiment

Thermoelectric device disclosed herein and various systems relevant with them and feature description are in the temperature control system content that is used for seat-assembly (for example automotive seat, bed, sofa etc.), because they have special effectiveness in this content.Yet,, also can be used for other content, such as but not limited to other heating and/or cooling device or system at this argumentation and/or the various embodiment that illustrate.

With reference to the explanation of figure 1, thermoelectric device can comprise a pair of terminal T1, T2, and it is positioned at the place, opposite end.Among the some or all of embodiment disclosed herein, thermoelectric device 1 comprises amber ear card circuit.Yet thermoelectric device 1 can comprise dissimilar circuit or configuration.Therefore, the feature and the advantage electricity that can be applied to any kind that are described in this arrange, it is used for selectively heating and/or cools off a large amount of air or other fluid.In the embodiment show in figure 1, direct voltage can be applied in the two ends of the thermoelectric device 1 between terminal (end terminal) T1, the T2 endways.As described in more detail in this, the polarity that the cooling of thermoelectric device 1 or heats can be by switching in the voltage that terminal T1, T2 place apply and selectively putting upside down.

As shown in Figure 1, thermoelectric device 1 can comprise a plurality of different conductor elements 2,4, its setting of connecting.Pair of conductors element 2,4 can link together by a series of relative conductor braces (tab) 8, and it can be successively between a pair of relative substrate (see figure 8).Each substrate can be thermally connected to fin or other heat transfer component (not shown) by heat conducting element.

In some were arranged, thermoelectric device 1 was arranged to fixing voltage operation, for example, and the voltage of the battery of electrical connection (for example, if the automobile-used storage battery of the standard of use is about 13.5V).The impedance of thermoelectric device 1 or other electrical characteristics can be selected so that produce best cooling effect with specific voltage.Yet in the fixed voltage system, when the sense of current by thermoelectric device 1 is reversed (for example, in order to produce heat), the impedance of selection typically is not best.

Fig. 2 shows another embodiment of thermoelectric device 10, comprises surpassing two electric terminals T1, T2, T3.As described here, this configuration can permit being used for multistage heating and/or cooling.In Fig. 2, thermoelectric device 10 comprises altogether three terminal T1, T2, T3.Two terminal T1, T2 are end-terminal, generally are positioned at the place, opposite end of circuit.The 3rd terminal T3 is the intermediate terminals (intermediate terminal) that is located between terminal T1, the T2.

In certain embodiments, the driving voltage of the 3rd terminal T3 can contact, pass through electronic switch 16 and/or other method or Equipment Control by rigid line.The thermoelectric device 10 that comprises one or more intermediate terminals T3 can be used for the one or more required part of exciting circuit selectively.Therefore, be different from two conventional terminal thermoelectric devices (Fig. 1), when the magnitude of current constant of the equipment of being transported to 10, this improved thermoelectric device 10 can be set to change heating and/or cooling effect.Be understandable that the position of the 3rd terminal T3 (or any other intermediate terminals) can be as required or special application or instructions for use and change.For example, intermediate terminals T2 can be located between end-terminal T1, the T2 approximately midway.In another embodiment, intermediate terminals T3 can be positioned at more close end terminal T1, T2 one.

Continuation is with reference to figure 2, and electronic switch 16 can be a semiconductor switch, for example integrated field-effect transistor (FET) switch etc.Therefore, as discussing, switch 16 can be used for changing the impedance by thermoelectric device 10.For example, when needs cooling effect (for example voltage guiding is between end terminal T1, T2), the impedance of equipment 10 can increase, and perhaps when needs heats (for example voltage guiding is between end terminal T1, T2 and intermediate terminals T3), the impedance of equipment 10 can reduce.Therefore, heating as required and/or cooling effect can a part of delivered currents by thermoelectric device 10.

Further with reference to figure 2, thermoelectric device 10 can comprise first thermoelectric material 12 and second thermoelectric material 14, and both are connected in series by a plurality of conductor elements 18.As discussing, equipment 10 may further include at the first terminal T1 at circuit one end place, at the second terminal T2 at circuit other end place and the 3rd terminal T3 that is provided with along the centre position between the first and second terminal T1, T2 roughly.In certain embodiments, the first terminal T1 is connected to first voltage, and the second terminal T2 is connected to second voltage.Further, the 3rd terminal T3 can be connected to second voltage by switch 16 (for example rigid line contact, electronic switch 16 etc.).

Therefore, when moving, switch 16 can cut off so that be applied to (for example end-terminal) between the first and second terminal T1, the T2 at the pressure reduction between first and second voltages with first pattern (for example cooling) when equipment 10.So electric current can be by whole or entire circuit (for example, by series connection first and second thermoelectric materials 12,14) basically.On the contrary, when equipment 10 during with second pattern (for example heating) operation, switch 16 can closure so that electric current is only used the part (for example, between the second and the 3rd terminal T2, T3) by circuit.As needs or require special application or when using, this can reduce the impedance of equipment 10 effectively and produce heating and/or cooling for the varying level of special fixed voltage.

With reference to figure 3, the switching of intermediate terminals T3 can utilize semiconductor switch 26 or other similar device and realize.In addition, as shown in Figure 4, the switching of the selection of intermediate terminals T3 can realize by rigid line tap 36.In other embodiments, semiconductor switch can be incorporated in the thermoelectric material of equipment.In this layout, can eliminate the needs that transmit lead for heavy current.

Be understandable that, when needs or when requiring, by can be reverse, to produce different heating and/or cooling effect in the sense of current of this description and/or any equipment of illustrating.Therefore, thermoelectric device can be sizing, design, and otherwise be provided with and be used for special heats with specific fixed voltage.When electric current was reversed to produce cooling effect, thermoelectric device can comprise one or more intermediate terminals, the part by circuit only with the stream of guide body selectively.Therefore, for specific voltage, the heating and cooling effect that needs can be used identical thermoelectric device and obtain.

As discussing, the thermoelectric device that comprises one or more intermediate terminals can be sizing, design, and otherwise be configured to roughly best cooling of (for example, the voltage that provides by car battery or other DC power supply) generation and/or heats under fixed voltage.Not having under the situation of intermediate terminals, when electric current is reversed, may be difficult to produce the relative thermal conditioning effect (for example, heating and/or cooling) of needs.This is because in the fixed voltage system, is used for the impedance of the opposite temperature conditions effect of generation needs when the impedance that the first temperature conditions pattern (for example cooling) produces the temperature conditions effect of needs is unlike in second pattern (for example heating).Therefore, use intermediate terminals and switch or other electric current route (routing) equipment so that change impedance selectively, so that produce heating and/or the cooling effect that needs by equipment.

In certain embodiments, the energy resource system that is used for automobile or other vehicle typically comprises battery, and battery provides about 13.5 volts of voltages when alternating current generator suitably moves.In some was arranged, two circuit (for example disclosed circuit of Fig. 1) can be connected in series so that the only about half of voltage of battery to be provided at the circuit two ends effectively.Thermoelectric device can be arranged in specific voltage (for example, by the car battery service voltage) optimum or approaching optimum cooling is provided.Yet this may influence can be by the heat that circuit obtained when electric current is reversed.Therefore, utilization comprises the thermoelectric device of intermediate terminals, and as this illustrate and discuss, circuit can be designed to, when in relative temperature condition pattern (for example heat and/or cool off) operation, provide needed cooling and/or heats and non-any sacrifice in performance with the battery full voltage.This embodiment can reduce the needs that series circuit is set, and produces complicated control module still less.In addition, best or approaching best cooling under specific voltage and/or heating can utilize identical substrate and realize.

The circuit theory diagrams of different embodiment of

thermoelectric device

50A, 50B, 50C that comprise

intermediate terminals

56A, 56B, 56C are shown in Fig. 5 A-5C.In Fig. 5 A, the thermoelectric device 50A of description comprises two end-

terminal

52A, 54A and an intermediate terminals 56A.In sketch map is shown, intermediate terminals 56A between two end-

terminal

52A, 54A approximately midway.Yet in other embodiments, as the needs or the requirement of special applications, intermediate terminals 56A can be positioned at more near two end-terminal 52A, of 54A.

As discussing, in order to encourage thermoelectric device 50A, electric current may be provided between two terminals.In Figure 50 A, the direction guide body stream roughly to represent between two end-

terminal

52A, 54A by arrow 58A (for example, from 52A to 54A).Therefore, under this operational process, the direction that electric current disapproves at intermediate terminals 56A flows.In one embodiment, the flowing of electric current in arrow 58A direction produces cooling effect along first side of thermoelectric device 50A.

When the sense of current is reverse, as shown in Fig. 5 B (for example, generally by arrow 58B represent from the direction of an end-terminal 54B towards 52B), can produce heats along first side of thermoelectric device 50B.

As discussed in more detail in this, path of current can be from end-

terminal

52C, 54C to intermediate terminals 56C, and/or be routed to

end terminal

52C, 54C from middle terminal 56C.For example, in the embodiment shown in Fig. 5 C, electric current can be directed to intermediate terminals 56C from end-terminal 54C in the direction of generally representing by arrow 58C.This can make the user guide body flow a part of only passing through thermoelectric device 50C.Therefore, the degree of thermoelectric device 50C generation heating and/or cooling effect can be controlled selectively.For example, if it is identical being delivered to the electric current of end-terminal 54B, 54B, if and thermoelectric device 50B, 50C be similar setting, the heats that produces along thermoelectric device 50C first side shown in Fig. 5 C possible less than the heats that is produced along equipment 50B first side among Fig. 5 B.Similarly, in Fig. 5 A, if electric current is directed to intermediate terminals 56A from end-terminal 52A, the cooling effect along thermoelectric device 50A first side can be reduced so.

In Fig. 6 A, the thermoelectric device that illustrates comprises the intermediate terminals 66A that is positioned at more near an end-terminal 64A.This design and configuration can be used for being controlled at selectively the heating and/or the cooling level of thermoelectric device place or the generation of its vicinity.In Fig. 6 A, electric current is routed to intermediate terminals 66A in the direction of generally being represented by arrow 68A from an end-terminal 62A.Thus, heating that produces by thermoelectric device 60A and/or cooling level may be greater than by being directed to heating that electric current produced and/or the cooling level of intermediate terminals 66A from opposing ends terminal 64A.

Fig. 6 B shows the embodiment of thermoelectric device 60B, and it comprises two intermediate terminals 65B, 66B.Other embodiment in this discussion and shown, intermediate terminals 65B, 66B can be positioned at along any position of thermoelectric device 60B length.Further, if according to the needs or the requirement of application-specific or use, thermoelectric device 60B can comprise more or less intermediate terminals 65B, 66B.

As discussing, any direction transmission that electric current can be between two terminal 62B, 64B, 65B, 66B.For example, electric current can be directed to another end-terminal 64B, 62B from any end-terminal 62B, 64B, or is directed to intermediate terminals 65B, 66B from any end-terminal 62B, 64B.Similarly, electric current can be directed to any end-terminal 62B, 64B from any intermediate terminals 65B, 66B, or is directed to any other intermediate terminals 66B, 65B from any intermediate terminals 65B, 66B.

For example, illustrate as Fig. 6 B, under an operational process, electric current can be directed to an intermediate terminals 65B from an end-terminal 62B in the direction of generally being represented by arrow 67B.Similarly, under different operational processes, electric current can be directed to another intermediate terminals 66B from another end-terminal 64B in the direction of generally being represented by arrow 68B.As discussing, under other operational process, thermoelectric device 60B can be set with delivered current between any two electric terminals 62B, 64B, 65B, 66B, and no matter whether they are end-terminal or intermediate terminals.

Fig. 7 A and 7B show the embodiment of circuit diagram, and wherein electric current can transmit simultaneously by two of thermoelectric device 70A, 70B different parts.For example, in Fig. 7 A, electric current is directed to intermediate terminals 76A in the direction of generally being represented by arrow 78A from an end-terminal 72A, produces heating or cooling effect with first side along equipment 70A.Simultaneously, electric current is directed to identical intermediate terminals 76A in the direction of generally being represented by arrow 79A from an end-terminal 74A, produces relative thermodynamic effect with first side along equipment 70A.Therefore, under such operational process, the part of thermoelectric device 70A can be heated, and another part can be cooled.Illustrate as Fig. 7 B, when current reversal, the part of thermoelectric device 70B cooling and heating also can reverse expediently.
